GoDaddy's SMTP server to send email Error

I want to send email with my web application. It is published on rackspace dedicated server but I'm using GoDaddy's SMTP server to send email.

The fault I'm getting is:

System.Net.Mail.SmtpFailedRecipientException: Mailbox name not allowed. The server response was: sorry, relaying denied from your location [xx.xx.xxx.xx] (#5.7.1)

This is my code 

SmtpClient client = new SmtpClient("relay-hosting.secureserver.net", 25); 
string to ="[email protected]"; 
client.DeliveryMethod = SmtpDeliveryMethod.Network;
client.Credentials = new System.Net.NetworkCredential("[email protected]","**");

MailAddress fromAddress = new MailAddress("[email protected]", "CompanyName"); 
MailMessage message = new MailMessage(); 
message.From = fromAddress; 
message.To.Add(to); 
message.Body = "This is Test message";
message.Subject = "hi";

client.Send(message); message.Dispose(); return "Email Send";

Should I do any configuration on dedicated server?

That is so simple:

You must focus on smtp host, port, ssl... Change smtp host to: relay-hosting.secureserver.net And DELETE port and ssl, thats all... Do not use smtp port and smtp ssl true or false

    var fromAddress = "mailfrom@yourdomain";
    // any address where the email will be sending
    var toAddress = "mailto@yourdomain";
    //Password of your mail address
    const string fromPassword = "******";
    // Passing the values and make a email formate to display
    string subject = TextBox1.Text.ToString();
    string body = "From: " + TextBox2.Text + "\n";
    body += "Email: " + TextBox3.Text + "\n";
    body += "Subject: " + TextBox4.Text + "\n";
    body += "Message: \n" + TextBox5.Text + "\n";
    // smtp settings
    var smtp = new System.Net.Mail.SmtpClient();
    {
        smtp.Host = "relay-hosting.secureserver.net";
**//Warning Delete =>//smtp.Port = 80;**
**//Warning Delete =>//smtp.EnableSsl = false;**
        smtp.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network;
        smtp.Credentials = new NetworkCredential(fromAddress, fromPassword);
        smtp.Timeout = 20000;
    }
    // Passing values to smtp object
    smtp.Send(fromAddress, toAddress, subject, body);

Start trying to change your port 465 instead 25.

Or remember Relay-hosting is very limited to 250 emails per day and not accept remote connections so easy. Check if you can use SSL connection.

If you are hosting with RackSpace you should use the SMTP RackSpace recommends for sending from their servers. Unfortunately, you can only use relay-hosting.secureserver.net if you are sending from go Daddy Shared or 4GH hosting.

Are you testing locally? If yes, then your SMTP server may not allow relaying. Do not worry when you will deploy the application there won't be any problem.
